Specification of Letters Patent.

Patented Nov, 1. 1921.

Application filed October 29, 1920. Serial No. 420,i01.

To all whom it may concern:

Be it known that I, JACOB F. MARTIX. a

citizen of the United States, residin at automobile buffers. and moreparticularly to that class or type which are designed to be attached toand carried by the front and rear portions of the motor vehicle for thepurpose of protecting the latter and also cushioning the shock or impactdue to coming into contact with another vehicle. pedestrian, or otherobject.

The primary object of the invention is to provide a generally improvedbuffer of this class, which will be exceedingly simple in construction,cheap of manufactureQand efficient in use.

Afurtherobject is to provide an improved one-piece butter-bar ofimproved form including open end loops te inating in inwardly extendingattachin ii arms of ogee form.

A further and very important object is the provision of improvedbuffer-bar carrying, supporting and cushioning supplemental springmembers particularly designed and adapted for attachment to the scrollportions of sprin members of the scroll elliptic type where y such mainand supplemental spring or attaching members are adapted to cooperatewith each other in giving added strength and resiliency to theattachments, as well as reducing the liability of breakage ordamage tothe springs to a minimum.

A still further and very important. object is the provision of animproved butter-bar attaching and cushioning device which may be readilyand uickly attached to and detached from springs of this general type.

With the above mentioned and other ends in view, the invention consistsin the novel construction, arrangement and combination of parts,hereinafter described, illustrated in one of its er 'iodiments in theaccompanying drawings. and particularly pointed out in the appendedclaims.

Referring to the drawings, forming a part of this spec cation. Figure 1,is a fragmentary to plan view of the improved buffer-bar and itssupplemental spring attaching members. the middle or median portion ofthe bufl'er-bar being broken en oy and the end loops drawn togetherfor'thc purpose of illustration.

Fig. :2. a side elevation of the improved butterdiar and its attachmentsas applied to springs of the scroll elliptic" type.

Fig. 3, a fragmentary front elevation of the improved butter-bar and theimproved supplemental spring attaching mei'nbcrs and clamps forattaching the latter to the scroll portions'of the elliptic springs.

Similar numerals of reference designate like parts throughout all thefigures of the d ra Wi n gs.

The improved buffer-bar is of the onepiece typeand comprises a singlelength of materialforming the main body portion 1, of the buffer-bar,and having the endsthereof bent upon themselves forming open end loops1, said loops terminating in inwardly extending spring arms of generalogec form, the inner ends of said arms 1". terminating in attachingmembers 1.

As a means of suitably mounting and attuching the ends 1, of thebuffer-bar to the scroll portion of springs of the scroll elliptic typewhereby the latter will cooperate with the former in giving addedstrength and resiliency to the parts. the invention includes a pair ofbuffer-bar supporting supplemental Spring members 2. having curvedportions 2, conforming to the general contour of the scroll portion 3,of the elliptic spring 3, said curved portion 2, terminating at its endin a loop-eye 2", adapted to receive and contain the sleeve of the upperspring and between the shackle or link members 4, as illustrated mostclearly in Fig. 2 of the drawin As a means 0 attaching the supplementalspring or bracket members 2, to the scroll portions 3*. of the springs3, suitable clamping members are provided, said clamping members, in thepresent instance, comprising U-shaped clamps 5, extending over the edgesof the parts 2 and 3, said clamps having their sides threaded andextending through suitable openings in clamp plates 6.'and provided withclamping nuts 6.

As a means of attachin the ends 1, of the bufl'cnbar to the upper endsof the supplemental spring or bracket members 2, the latter'are providedwith suitable openings adapted to register with suitable openings in themils of ninl vontnin sonar! ntzmlling riled with 1 Minn clumpingn Whilemi, improved illllT-lJilF in portion- 5 lurlv (i from! and :nlupterl foruse 11 a run in wonner-tion will] this type of Froqm-ntly elnploved atthe roar illll lfifi will at onvo lJk apparent n wpnill well ruluplozlfor isobar i} mnnmalion will!
